PNEUMATIC-TIRE FASTENING.

SPECIFICATION forming part of Letters Patent No. 658.750, dated Octob 2, 1900.

Application filed January 15, 1900- Serial No. 1,521. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH A. BERGER, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pneumatic- Tire Fastenings, of whichthe following is a specification.

My invention relates particularly to means for attaching pneumatic-tire jackets to the rims of wheels by the use of studs engaging the jacket through eyelets therein.

The object of the present invention is the provision of improved studs and a novel manner of fastening the tire-jacket to the rim and securing the studs in position on the latter. I accomplish this object by the device shown in the accompanying drawings, in Which- Figure 1 is a cross-section of the rim and tire-jacket secured together according to my invention. Fig. 2 is a longitudinal central section of same. Fig. 3 is a perspective View of one edge of the tire-jacket, showing a metallic eyelet secured thereto. Fig. 4E is a perspective view of one of the studs.

The tire-jacket 1 has its lower edge 2 and its upper edge 3 each provided with a series of eyelets 4, located at uniform intervals,

around said edges. The studs 5 are inserted in the eyelets of the edge 2. The heads 6 of said studs are of less diameter than the eyelets, so that the former will readily pass through the eyelets. The bases 7 of the studs are of greater diameter than the eyelets. The edge 2 is fastened to the rim 8, between the eyelets, by the tacks or screws 9. The edge 3 is free to be removed from the studs when the inner inflatable tube 10 is deflated. A protecting-flap 11 is secured to the tire-jacket inward of the eyelets along the edge 2. The studs 5 are entirely independent of the jacket and rimthat is, are not permanently fastened thereto. I am thus enabled to provide a comparatively cheap construction, inasmuch as the studs can be made very cheaply and not have to be specially constructed and of an expensive character in order to be secured to the rim. Similarly the fastenings 9 afford a cheap, substantial, and. efficient means for securing the jacket to the rim,while any one or more can be easily removed if found necessary or desirable. These fastenings prevent all lateral or circumferential movement of the tire-jacket.

The operation of the device is as follows: When the edge 2 has been secured to the rim, as above described, the heads 6 of the studs will project above same. The bases 7 will rest loosely between the edge 2 and the rim 8. The operator will now insert the inflatable tube 10 over the flap 11. He will then raise the said flap and tube 10 and insert the edge 3, passing the eyelets therein over the heads 6 of the studs. When the tube 10 is inflated, the edge 3 will be drawn over toward the right of Fig. 1, thus moving the studs in that direction and causing the heads 6 to project over the left side of the upper eyelets. This serves to lock the edge 3 under said heads. If the tire becomes punctured at any part, the operator will deflate the inner tube, thus permitting him to detach the edge 3 near the punctured part. The inner tube 10 will then be drawn out of the casing at the punctured part, when the puncture can be mended without disturbing the other parts of said tube and tire-jacket; but if it is found necessary to remove the jacket in whole or in part it can be readily done by removing the fastenings 9.

It will be understood that some of the details of my device may be altered without departing from the spirit of my invention. I therefore do not confine myself to such details except as hereinafter limited in the claim.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination with a wheel-rim; of a pneumatic-tire jacket having a series of eyelets along each edge; removable fastenings securing one of said edges to the rim at points intermediate of its eyelets and the other edge overlapping said secured edge; and a series of studs having heads of less diameter than the eyelets, and having bases of greater diameter than the eyelets, and resting loosely upon the rim; said studs being independent of both rim and tire-jacket and having their shanks passing through both series of eyelets and their bases held against the rim by the secured edge of the jacket, substantially as and for the purpose specified.

Signed by me at Chicago this 11th day of January, 1900.

JOSEPH A. BERGER.
